regexbashgrep

Bash, grep between two lines with specified string

Example:

a43
test1
abc
cvb
bnm
test2
kfo

I need all lines between test1 and test2. Normal grep does not work in this case. Do you have any propositions?

Solution

  • Print from test1 to test2 (Trigger lines included)

    awk '/test1/{f=1} /test2/{f=0;print} f'
awk '/test1/{f=1} f; /test2/{f=0}' 
awk '/test1/,/test2/'


    test1
abc
cvb
bnm
test2

    Prints data between test1 to test2 (Trigger lines excluded)

    awk '/test1/{f=1;next} /test2/{f=0} f' 
awk '/test2/{f=0} f; /test1/{f=1}' 


    abc
cvb
bnm
